Integrated Electronic Load Controller with T-Connected Transformer for Isolated Asynchronous Generator

چکیده
This paper deals with a integrated Electronic Load Controller (IELC) for an isolated asynchronous generator (IAG), used in constant power pico hydro power generation for feeding three-phase four-wire loads. The proposed IELC is used to control the voltage and frequency of IAG in the integrated manner. This IELC is realised using a T-connected transformer and three-leg insulated gate bipolar transistors (IGBTs) based current controlled voltage source converter (VSC) a capacitor, a chopper switch and an auxiliary load on its dc bus. The proposed IELC with an isolated generating system is modeled and simulated in MATLAB along with Simulink and power system blockset (PSB) toolboxes. The simulated results of IAG-IELC system are presented to demonstrate its performance for feeding three-phase four-wire linear/nonlinear (balanced/unbalanced) loads with the neutral current compensation.
